ventilation at all. The best method of supplying return air is through the heating, ventilation and air conditioning (HVAC) system. Through the HVAC system, the air can be temperature- controlled for summer and winter. Return air can also be brought in directly from outside the building, but detrimental effects can result from extreme seasonal hot and cold tempera- tures from the outdoors.

NOTE: Return air from the mechanically driven system must not blow at the opening of the baking chamber. Poor oven baking performance will result.

C.Other ventilation concerns

•Special locations, conditions, or problems may require the services of a ventilation engineer or specialist.

•Inadequate ventilation can inhibit oven performance.

•It is recommended that the ventilation system and duct work be checked at prevailing intervals as specified by the hood manufacturer and/or HVAC engineer or specialist.

III. ASSEMBLY

A.Legs/Casters Installation

1.Move the oven to its final location using the casters that are pre-attached to the bottom panel.

2.Elevate the oven until its bottom surface is at least 18" (457mm) above the floor.

3.Remove the casters from the bottom of the oven. These casters are attached for pre-installation movement ONLY, and may not be left on the oven.

4.Attach one of the 9" (229mm) leg extensions to the REAR DRIVE-END (rear left) corner of the oven, as shown in Figure 2-3. On the OUTSIDE hole of the leg extension, use one 3/4"-10 hex screw, one 3/4" lockwasher, and one 3/4" flat washer. On the INSIDE hole of the leg extension, use the 3/4"-10 shoulder eyebolt (supplied in the Installation Kit) in place of the screw.

5.Attach the 3 remaining leg extensions using the remaining screws, lockwashers, and flat washers.

6.Attach EITHER the 6" (152mm) adjustable legs OR the casters to the bottom of the 9" leg extensions, as follows:

•THE 6" (152mm) ADJUSTABLE LEGS may only be used if there is at least 24" (610mm) service access on ALL FOUR sides of the oven. To attach the adjustable legs, screw the threaded stud into the center hole of the leg extension. See Figure 2-4.

•CASTERS may be used in all installations. To attach the casters, use the 3/8"-16 hex screws, 3/8" lockwashers, and 3/8" flat washers supplied in the Installation Kit. See Figure 2-4. The two locking casters should be installed at the front of the oven.

7.Lower the oven to the floor.

•If the 6" (152mm) legs were used in the installation, adjust the "foot" section of each leg to level the oven.

•If the casters were used in the installation, lock the front casters in place.

B.Restraint Cable Installation

Because the oven is equipped with casters, a restraint cable assembly must be installed to limit the movement of the appliance without depending on the connector and the quick disconnect device or its associated piping. Anchor one end of the cable to the eyebolt on the left rear leg extension. Anchor the opposite end to the wall as shown in Figure 2-5, using the eyebolt supplied with the restraint cable assembly.
